Sparse 2-D arrays for 3-D phased array imaging - experimental validation

  title={Sparse 2-D arrays for 3-D phased array imaging - experimental validation},
  author={Andreas Austeng and Sverre Holm},
  journal={IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control},
To be able to describe more precisely the behavior of a real-time 3-D ultrasound system with either a dense array or various sparse designs, experimental data from a 2-D fully connected array prototype with 50/spl times/50 elements have been collected. The data have been processed off line to form synthetic aperture 3-D volume images. Simulated and experimental results are compared and show good correlation. The performance of the best sparse designs, all thinned to more than 50%, offer… CONTINUE READING
